Chigiri, Kunigami, and Reo's team fully utilizes each other's weapons of speed, physique, and eyes for tactics. On the contrary, Isagi's team struggles due to the lack of coordination. Through observing and analyzing the opponent's combinations and his teammates' individual play, Isagi discovers a new way to use his weapon and evolve himself one step further. And the tide of ego in this game triggers others to evolve.
That's controlling someone 
and expecting them to change.
ذلك التحكّم بشخص والتوقّع منه أن يتغيّر

Eso es controlar a alguien
y esperar que cambie.

Isso é o mesmo que controlar 
alguém, esperando que ele mude.
я просто понадеялся,
что он изменится.
